RCA 5751 Black Plates
Premium 5751/12AX7 with 2 mica spacers and 2 support rods to ensure low microphonics. These are from German Government stock with falcon logos. One of the best ever made 5751 tubes. Low noise, good texture. Great for guitar and phono... A few singles labeled for National and Heintz & Kaufman are also available.

Realy amazing sound! Six month ago, i buy one of the same tubes on an other internet shop in the usa for 95$... Koray sell the same in better condition just for 38$... This tube is great with my Fender Champ 1957.Thanks Koray for your good deal and perfect tubes.

Dear SergiiI all so own an Leben cx300. Did you try some other than this and standard sovtec? Because I've very sensitive speakers I hope this give a bit less humm in the spaeker than the standard one. I thought the 5751 as only 70 mu and hoped that why they give less humm. Best regards Yves

I had a gut feeling I should try this tube. I installed this RCA 5751 Black Plate in my AC15, and that's where it will stay. Awesome breakup! Perfect dynamics, perfect balance! It's as if this tube was made for my amp. Might I add: shipping was fast, Koray is a pleasure to deal with, and tube quality/price is unsurpassed. Very happy customer.

I purchased a pair of 5751 RCA black plates branded National years ago. They are doing a fine job now in a pair of Quicksilver Mono 90's. Great quality tubes. Just would buy from Koray without hesitation!
